FIELD

The subject matter disclosed herein is generally related to systems, methods, and compositions for correction frameshift mutations, accurate genome editing and treatment of diseases.

BACKGROUND

Frameshift mutations are genetic mutations that are caused by insertion or deletion (indels) of nucleotides in a coding region of a nucleic acid sequence that is not divisible by three. The indel results in mutated sequences that, due to the triplet nature of gene expression by codons, changes the reading frame of the codon and therefore change the translation of the nucleic acid sequence.

Frameshift mutations are present in number of diseases, but genetic treatments for these diseases are limited. They often involve removing large section from a genome sequence and lead to undesired side effects.

Therefore, there is need for more efficient tools to correct frameshift mutations.

Hofker and Jan van Deursen, Transgenic Mouse Methods and Protocols, 2nd edition (2011).

As used herein, the singular forms “a”, “an,” and “the” include both singular and plural referents unless the context clearly dictates otherwise.

The term “optional” or “optionally” means that the subsequent described event, circumstance or substituent may or may not occur, and that the description includes instances where the event or circumstance occurs and instances where it does not.

The recitation of numerical ranges by endpoints includes all numbers and fractions subsumed within the respective ranges, as well as the recited endpoints.

The terms “about” or “approximately” as used herein when referring to a measurable value such as a parameter, an amount, a temporal duration, and the like, are meant to encompass variations of and from the specified value, such as variations of +/−10% or less, +/−5% or less, +/−1% or less, +/−0.5% or less, and +/−0.1% or less of and from the specified value, insofar such variations are appropriate to perform in the disclosed invention. It is to be understood that the value to which the modifier “about” or “approximately” refers is itself also specifically, and preferably, disclosed.

The term “staggered end” when it refers to a double stranded DNA (dsDNA) molecule refers to the 5′ and or 3′ ends of that molecule having at least one nucleotide that is not hybridized to the opposite strand of the dsDNA.

The term “blunt end” when it refers to a dsDNA molecule refers to the 5′ and or 3′ ends of that molecule having nucleotides that hybridize to the opposite strand of the dsDNA.

The term “variant” as used herein means a polypeptide or nucleotide sequence that differs from a given polypeptide or nucleotide sequence in amino acid or nucleic acid sequence by the addition (e.g., insertion), deletion, or conservative substitution of amino acids or nucleotides, but that retains the biological activity of the given polypeptide (e.g., a variant nucleic acid could still encode the same or a similar amino acid sequence). A conservative substitution of an amino acid, i.e., replacing an amino acid with a different amino acid of similar properties (e.g., hydrophilicity and degree and distribution of charged regions) is recognized in the art as typically involving a minor change. These minor changes can be identified, in part, by considering the hydropathic index of amino acids, as understood in the art (see, e.g., Kyte et al., J. Mol. Biol., 157: 105-132 (1982)). The hydropathic index of an amino acid is based on a consideration of its hydrophobicity and charge. It is known in the art that amino acids of similar hydropathic indexes can be substituted and still retain protein function. The present disclosure provides amino acids having hydropathic indexes of 2 are substituted. The hydrophilicity of amino acids also can be used to reveal substitutions that would result in proteins retaining biological function. A consideration of the hydrophilicity of amino acids in the context of a peptide permits calculation of the greatest local average hydrophilicity of that peptide, a useful measure that has been reported to correlate well with antigenicity and immunogenicity (see, e.g., U.S. Pat. No. 4,554,101). Substitution of amino acids having similar hydrophilicity values can result in peptides retaining biological activity, for example immunogenicity, as is understood in the art. The present disclosure provides substitutions are performed with amino acids having hydrophilicity values within ±2 of each other. Both the hydrophobicity index and the hydrophilicity value of amino acids are influenced by the particular side chain of that amino acid. Consistent with that observation, amino acid substitutions that are compatible with biological function are understood to depend on the relative similarity of the amino acids, and particularly the side chains of those amino acids, as revealed by the hydrophobicity, hydrophilicity, charge, size, and other properties. “Variant” also can be used to describe a polypeptide or fragment thereof that has been differentially processed, such as by proteolysis, phosphorylation, or other post-translational modification, yet retains its biological activity or antigen reactivity. Use of “variant” herein is intended to encompass fragments of a variant unless otherwise contradicted by context. The term “protospacer-adjacent motif” as used herein refers to a DNA sequence immediately following a DNA sequence targeted by a nuclease. Examples of protospacer-adjacent motif include, without limitation, NNNNGATT, NNNNGNNN, NNG, NG, NGAN, NGNG, NGAG, NGCG, NAAG, NGN, NRN, NNGRRN, NNNRRT, TTTN, TTTV, TYCV, TATV, TYCV, TATV, TTN, KYTV, TYCV, TATV, and TBN.

The term “MS2 stem loop” as used herein refers to a pattern in a single stranded nucleotide strand originated from a bacterial virus when two regions of the same strand base-pair to form a double helix that ends in an unpaired loop.

Alternatively or additionally, a “variant” is to be understood as a polynucleotide or protein which differs in comparison to the polynucleotide or protein from which it is derived by one or more changes in its length or sequence. The polypeptide or polynucleotide from which a protein or nucleic acid variant is derived is also known as the parent polypeptide or polynucleotide. The term “variant” comprises “fragments” or “derivatives” of the parent molecule. Typically, “fragments” are smaller in length or size than the parent molecule, whilst “derivatives” exhibit one or more differences in their sequence in comparison to the parent molecule. Also encompassed modified molecules such as but not limited to post-translationally modified proteins (e.g. glycosylated, biotinylated, phosphorylated, ubiquitinated, palmitoylated, or proteolytically cleaved proteins) and modified nucleic acids such as methylated DNA. Also, mixtures of different molecules such as but not limited to RNA-DNA hybrids, are encompassed by the term “variant”. Typically, a variant is constructed artificially, preferably by gene-technological means whilst the parent polypeptide or polynucleotide is a wild-type protein or polynucleotide. However, also naturally occurring variants are to be understood to be encompassed by the term “variant” as used herein. Further, the variants usable in the present disclosure may also be derived from homologs, orthologs, or paralogs of the parent molecule or from artificially constructed variant, provided that the variant exhibits at least one biological activity of the parent molecule, i.e. is functionally active.

Alternatively, or additionally, a “variant” as used herein, can be characterized by a certain degree of sequence identity to the parent polypeptide or parent polynucleotide from which it is derived. More precisely, a protein variant in the context of the present disclosure exhibits at least 80% sequence identity to its parent polypeptide. A polynucleotide variant in the context of the present disclosure exhibits at least 70% sequence identity to its parent polynucleotide. The term “at least 70% sequence identity” is used throughout the specification with regard to polypeptide and polynucleotide sequence comparisons. This expression preferably refers to a sequence identity of at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% to the respective reference polypeptide or to the respective reference polynucleotide.

The similarity of nucleotide and amino acid sequences, i.e. the percentage of sequence identity, can be determined via sequence alignments. Such alignments can be carried out with several art-known algorithms, preferably with the mathematical algorithm of Karlin and Altschul (Karlin & Altschul (1993) Proc. Natl. Acad. Sci. USA 90: 5873-5877), with hmmalign (HMMER package, http://hmmer.wustl.edu/) or with the CLUSTAL algorithm (Thompson, J. D., Higgins, D. G. & Gibson, T. J. (1994) Nucleic Acids Res. 22, 4673-80) available e.g. on http://www.ebi.ac.uk/Tools/clustalw/ or on http://www.ebi.ac.uk/Tools/clustalw2/index.html or on http://npsa-pbil.ibcp.fr/cgi-bin/npsa_automat.pl?page=/NPSA/npsa_clustalw.html. Preferred parameters used are the default parameters as they are set on http://www.ebi.ac.uk/Tools/clustalw/ or http://www.ebi.ac.uk/Tools/clustalw2/index.html. The grade of sequence identity (sequence matching) may be calculated using e.g. BLAST, BLAT or BlastZ (or BlastX). A similar algorithm is incorporated into the BLASTN and BLASTP programs of Altschul et al. (1990) J. Mol. Biol. 215: 403-410. To obtain gapped alignments for comparative purposes, Gapped BLAST is utilized as described in Altschul et al. (1997) Nucleic Acids Res. 25: 3389-3402. When utilizing BLAST and Gapped BLAST programs, the default parameters of the respective programs are used. Sequence matching analysis may be supplemented by established homology mapping techniques like Shuffle-LAGAN (Brudno M., Bioinformatics 2003b, 19 Suppl 1:I54-I62) or Markov random fields. When percentages of sequence identity are referred to in the present application, these percentages are calculated in relation to the full length of the longer sequence, if not specifically indicated otherwise.

Overview

Some embodiments disclosed herein provide non-naturally occurring or engineered systems, methods, and compositions for target specific nucleases combined with blunting enzymes to correct frameshift mutations for genome editing and treatment of diseases. Frameshift mutations are genetic mutations that are caused by insertion and deletion (indels) of nucleotides in a DNA nucleic acid sequence that is not divisible by three. Due to the triplet nature of gene expression by codons, the indel can change the reading frame of the codon and therefore change the translation of the gene. Different types of frameshift mutations and examples of in-frame corrections of them are shown in FIGS. 1 and 2.

In some embodiments, the systems disclosed herein comprise a target specific nuclease, wherein the target comprises a double-stranded DNA (dsDNA) as well as a blunting enzyme. The systems disclosed herein can also comprise targeting moiety and/or a microhomology-mediated end joining (MMEJ) inhibitor.

In some embodiments, the target specific nuclease can be a CRISPR associated protein (Cas). In some embodiments, the targeted nuclease is a Cas9 protein as illustrated in FIGS. 3A-3D. In some embodiments, the blunting enzyme is joined to the targeted nuclease by a linker. In some embodiments, the blunting enzyme is separate from the targeted nuclease. In some embodiments, the composition further comprises a MMEJ inhibitor. In some embodiments, the composition further comprises a single guide RNA (sgRNA). In some embodiments, the composition further comprises a sgRNA and a MS2-binding protein, wherein the sgRNA comprises one or more MS2 stem loops. The MS2-binding protein is linked to the sgRNA by the one or more MS2 stem loops and binds to the blunting enzyme to form a blunting enzyme fused-MS2 binding protein.

The target specific nuclease combined with a blunting enzyme can correct frameshift mutations in genes in cells and tissues. In some embodiments, cells include eukaryotic cells, mammalian cells, and human cells. The target specific nuclease combined with a blunting enzyme can induce one or more single-base insertions and deletions (indels). In some embodiments, the targeted nuclease creates staggered ends when it cleaves the target dsDNA. When the staggered ends are created by the target specific nuclease, a blunting enzyme can be used to ether “fill in” the staggered end with a polymerase or “chew back” the staggered end with a nuclease. Filling in followed by ligation creates a one or more bp insertion and chewing back followed by ligation creates one or more bp deletion. (See FIGS. 4-5). In some embodiments, the target specific nuclease and a blunting enzyme induce a precise and predictable mutation in a dsDNA without the use of a donor template.

Microhomology-mediated end joining (MMEJ) is one of the pathways for repairing double-strand breaks in DNA. In MMEJ, microhomologous sequences are used to align broken ends often resulting in deletions flanking the original break. In some embodiments, if a target specific nuclease were used to cleave dsDNA, MMEJ could create an unintended deletion.

Non-homologous end joining (NHEJ) is another pathway for repairing double-strand breaks in DNA. In NHEJ, the broken ends are directly ligated together without use of a homologous template. In some embodiments, if a target specific nuclease were used to cleave dsDNA, NHEJ would directly ligate the cleaved dsDNA without deletions and therefore accurately edit the target sequence. (See FIGS. 6 and 7).

In some embodiments, an inhibitor of MMEJ is used to keep cleaved DNA from undergoing MMEJ and being subject to unintended deletion of the sequence of the dsDNA flanking the cleavage.

Target Specific Nucleases

In some embodiments, a target specific nuclease is a nuclease that cleaves a dsDNA and, at least in some cases, leaves a staggered end at the cleavage site. The target specific nuclease disclosed herein can be for example, without limitation, Cas12a, LbCas12a, FnCas12a, AsCas12a, Cas9, SpCas9, SaCas9, LZ3Cas9, Casφ, and the double combinations of Cas9 nickase, zinc finger nuclease (ZFN), and TAL Effector Nuclease (TALEN). The LZ3Cas9 disclosed here can be N690C, T769I, G915M, or N980K. In some embodiments, the target specific nuclease cleaves dsDNA in the genome of a cell providing staggered ends. In some embodiments, the target specific nuclease provides a dsDNA cleavage resulting in staggered ends more than 10% of the time. In some embodiments, the target specific nuclease provides a dsDNA cleavage resulting in staggered ends more than 20% of the time. In other embodiments, the target specific nuclease provides a dsDNA cleavage resulting in staggered ends more than 3, 40, 50, 60, 70, 80, 90, 95, or 99% of the time.

In some embodiments, the target specific nuclease is a CRISPR associated protein (Cas). In these embodiments, the Cas uses a guide RNA (gRNA) to provide specificity. In some embodiments, the gRNA is a single guide RNA (sgRNA) i.e., a fusion of two noncoding RNAs: a synthetic CRISPR RNA (crRNA) and a trans-activating CRISPR RNA (tracrRNA).

In general, a guide sequence is any polynucleotide sequence having sufficient complementarity with a target polynucleotide sequence to hybridize with the target sequence and direct sequence-specific binding of a Cas protein to the target sequence. In some embodiments, the degree of complementarity between a guide sequence and its corresponding target sequence, when optimally aligned using a suitable alignment algorithm, is about or more than about 50%, 60%, 75%, 80%, 85%, 90%, 95%, 97.5%, 99%, or more. Optimal alignment may be determined with the use of any suitable algorithm for aligning sequences, non-limiting example of which include the Smith-Waterman algorithm, the Needleman-Wunsch algorithm, algorithms based on the Burrows-Wheeler Transform (e.g., the Burrows Wheeler Aligner), ClustalW, ClustalX, BLAT, Novoalign (Novocraft Technologies, ELAND (Illunina, San Diego, Calif.), SOAP (available at soap.genoincs.org.cn), and Maq (available at maq.sourceforge.net). In some embodiments, a guide sequence is about or more than about 5, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 35, 40, 45, 50, 75, or more nucleotides in length. In some embodiments, a guide sequence is less than about 75, 50, 45, 40, 35, 30, 25, 20, 15, 12, or fewer nucleotides in length. The ability of a guide sequence to direct sequence-specific binding of a CRISPR complex to a target sequence may be assessed by any suitable assay.

In some embodiments, the sgRNA comprises a nucleic acid sequence selected from the group consisting of SEQ ID NOs: 54-64. For example, the sgRNA can comprise a nucleic acid sequence at least 50%, at least 51%, at least 52%, at least 53%, at least 54%, at least 55%, at least 56%, at least 57%, at least 58%, at least 59%, at least 60%, at least 61%, at least 62%, at least 63%, at least 64%, at least 65%, at least 66%, at least 67%, at least 68%, at least 69%, at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% identical to a nucleic acid sequence selected from the group consisting of SEQ ID NOs: 54-64.

In some embodiments, the target specific nuclease is Cas9. In some embodiments, the target nuclease is a scissile variant. In some embodiments, the Cas9 is a scissile variant of Cas9. In some embodiments, the scissile is for example, without limitation, ΔF916, LZ3Cas9, G915F, F916P, R918A, R919P, Q920P, N690C, T769I, G915M and N980K. In some embodiments, the LZ3Cas9 is N690C, T769I, G915M, or N980K.

The target specific nuclease can comprise an amino acid sequence selected from the group consisting of SEQ ID NOs: 95-106. For example, the target specific nuclease comprises an amino acid sequence at least 50%, at least 51%, at least 52%, at least 53%, at least 54%, at least 55%, at least 56%, at least 57%, at least 58%, at least 59%, at least 60%, at least 61%, at least 62%, at least 63%, at least 64%, at least 65%, at least 66%, at least 67%, at least 68%, at least 69%, at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% identical to an amino acid sequence selected from the group consisting of SEQ ID NOs: 95-106.

In some embodiments, the target specific nuclease is a zinc finger nuclease (ZFN). A single zinc finger contains approximately 30 amino acids and the domain functions by binding 3 consecutive base pairs of DNA via interactions of a single amino acid side chain per base pair. The modular structure of the zinc finger motif permits the conjunction of several domains in series, allowing for the recognition and targeting of extended sequences in multiples of 3 nucleotides. These targeted DNA-binding domains can be combined with a nuclease domain, such as FokI, to generate a site-specific nuclease, called a “zinc finger nuclease” (ZFNs) that can be used to introduce site-specific double strand breaks at targeted genomic loci. This DNA cleavage stimulates the natural DNA-repair machinery, leading to one of two possible repair pathways, NHEJ and HDR. For example, the ZFN can target the Rosa26 locus (Perez-Pinera et al. Nucleic Acids Research (2012) 40:3741-3752) or a dystrophin gene.

In some embodiments, the target specific nuclease is a TAL effector nuclease (TALEN). The TALEN can be used to introduce site-specific double strand breaks at targeted genomic loci. Site-specific double-strand breaks are created when two independent TALENs bind to nearby DNA sequences, thereby permitting dimerization of FokI and cleavage of the target DNA. TALENs have advanced genome editing due to their high rate of successful and efficient genetic modification. This DNA cleavage can stimulate the natural DNA-repair machinery, leading to one of two possible repair pathways: homology-directed repair (HDR) or the non-homologous end joining (NHEJ) pathway. The TALENs can be designed to target any gene involved in a genetic disease.

The TALENs can include a nuclease and a TALE DNA-binding domain that binds to the target gene in a TALEN target region. The target gene can have a mutation such as a frameshift mutation or a nonsense mutation. If the target gene has a mutation that causes a premature stop codon, the TALEN can be designed to recognize and bind a nucleotide sequence upstream or downstream from the premature stop codon. A “TALEN target region” includes the binding regions for two TALENs and the spacer region, which occurs between the binding regions. The two TALENs bind to different binding regions within the TALEN target region, after which the TALEN target region is cleaved. Examples of TALENs are described in International Patent Application No. PCT/US2013/038536, which is incorporated by reference in its entirety.

In some embodiments, the target specific nucleases include tags including for example, without limitation, 3×Flag, nuclear localization sequence (NLS), and the combination of 3×Flag and NLS.

Blunting Enzymes

In some embodiments, the blunting enzyme or double strand break-end blunting enzyme (both terms are used interchangeably herein), is an enzyme that is able either to remove or add nucleotides to a staggered end of a double stranded DNA molecule to produce a blunt end. In some embodiments, the blunting enzyme disclosed herein is a polymerase or a nuclease. In some embodiments, the DSB-blunting enzyme is a single-strand DNA specific nuclease.

In some embodiments, the blunting enzyme is a polymerase selected from polymerase λ (POLL), polymerase μ (POLM), polymerase ν (POLN), polymerase η (POLH), polymerase β (POLB), DNA polymerase θ (POLQ), DNA polymerase κ (POLK), DNA polymerase IV (Saccharomyces cerevisiae), DNA polymerase γ (POLG), DNA polymerase ι (POLI), DNA polymerase ξ, DNA polymerase ν (POLN), DNA nucleotidylexotransferase (DNTT), TENT4A, DNA ligase 4, fungi pol IV-like DNA polymerase (Neurospora crassa), DNA polymerase/3′-5′ exonuclease PolX (Bacillus subtilis), Family X DNA Polymerase (Deinococcus radiodurans), and T4 DNA polymerase (Scherichia virus T4). In some embodiments, the blunting enzyme is a nuclease. In some embodiments, the nuclease is a single-strand DNA specific nuclease. In some embodiments, the nuclease is selected from MGME1, EXOG, APEX1, APEX2, FEN1, DNA2, APE1, XRN1, XRN2, EXOG, EXO5, AP endonuclease, RecJ Exonuclease (RecJ), XseA, XseB, S1 nuclease (nucS), P1 nuclease, XRCC4, Ligase IV, Artemis, and Csm1.

Except as specified above, the blunting enzymes can be from any organism. In some embodiments, the organism is a mammal. In other embodiments, the mammal is a human.

Optimal enzymes can be selected that will enable the precision indel alleles to be stably increased in various cells and target sequences. In some embodiments, the blunting enzymes can be selected from variants such as mutants, truncations or chimeric variants of DNA polymerases and single-base specific DNA nucleases. Representative variants of DNA polymerases and single-base specific DNA nucleases, including but not limited to human POLM (H329G), human POLM (H329G, R389K), human BRCT(POLM)_POLL1, human BRCT(POLM)_POLL2, T4 DNA polymerase(Y320A), T4 DNA polymerase(A737V). Other variants include the family X polymerases ScPolλ, HsPolλ, HsPolμ, HsTdt and HsPolβ, shown schematically in FIG. 8. In some embodiments, the blunting enzymes or the variants thereof can be modified with protein tags such as Myc, Flag, VStag, nuclease localization sequence. For example, the blunting enzymes or the variants thereof can include but not limited to 3×Flag-NLS-EXOG, 3×Flag-NLS-T4 DNA polymerase, 3×Flag-NLS-T4 DNA polymerase(Y320A), VStag-APEX2-NLS-NLS, 3×Flag-NLS-XseA.

In some embodiments, the blunting enzyme is covalently bound to the target specific nuclease by a linker. In some embodiments, the linker is an amino acid, a peptide, or a polypeptide.

Microhomology-Mediated End Joining (MMEJ) Inhibitor

The target specific nuclease and blunting enzyme disclosed herein can be combined with a microhomology-mediated end joining (MMEJ) inhibitor. In some embodiments, the MMEJ inhibitor is a CtIP inhibitor (e.g., KLHL15, PIN1). In some embodiments, the MMEJ inhibitor is an MRN inhibitor (e.g., E1b55K+E40rf6).

Pathogenic Frameshift Mutations

The non-naturally occurring or engineered systems, methods, and compositions disclosed herein can be used to repair pathogenic genes in human cells and tissues, and can be used to correct the underlying genetic basis of many diseases, especially those conditions caused by a frameshift mutation. Pathogenic frameshifts can cause a wide variety of illnesses. One particular condition caused by a frameshift mutation is Parkinson's disease, caused by the frameshift mutation depicted in FIG. 9.

FIG. 10 illustrates the editing of a gene using CRISPR-Cas9 and a blunting enzyme without the use of a donor template. The Cas9 gene editing system corrects a 1 bp BRCA2 frameshift mutation (c.8015_8016insA) and a 2 bp NF1 frameshift mutation (c.2027delC). As the schematic in FIG. 10 demonstrates, a stop codon is prematurely generated due to the frameshift mutation. By using this technique, combining Cas9 and a blunting enzyme without the use of a donor template results in repair of the frameshift mutations.

Other conditions caused by frameshift mutations include, inter alia, the following: various cancers, Parkinson's disease, muscular dystrophy, cardiomyopathy, anemia, Crohn's disease, cystic fibrosis, tuberous sclerosis, Xia-Gibbs syndrome, dermatitis, atopic, ichthyosis vulgaris, Usher syndrome, hypothyroidism, ventricular tachycardia, hemochromatosis, retinitis pigmentosa, arthrogryposis, Robinow syndrome, peroxisome biogenesis disorders, Zellweger syndrome spectrum, cortisone reductase deficiency, deficiency of pyrroline-5-carboxylate reductase, Van der Woude syndrome, Neonatal hypotonia, MYH-associated polyposis, neutropenia, methylmalonic acidemia with homocystinuria, hypobetalipoproteinemia, medium-chain acyl-coenzyme A dehydrogenase deficiency, Sezary syndrome, Stargardt disease, glycogen storage disease, maple syrup urine disease, fibrochondrogenesis, Chudley-McCullough syndrome, spastic paraplegia, frontonasal dysplasia, monocarboxylate transporter 1 deficiency, urofacial syndrome, Hajdu-Cheney syndrome, radial aplasia-thrombocytopenia syndrome, Nager syndrome, White-Sutton syndrome, ichthyosis vulgaris, FLG-Related Disorders, Grange syndrome, Charcot-Marie-Tooth disease, achromatopsia, amelogenesis imperfecta, adult junctional epidermolysis bullosa, fumarase deficiency, and Senior-Loken syndrome.

The systems, methods, and compositions described herein can also be used to enhance out-frame mutations by avoiding indel in multiples of three by a predictable mutation. Out-frame mutation occurs when the reading frame of the target dsDNA is completely disrupted. Therefore, the systems, methods, and compositions described herein can produce knockout cell lines and organisms.

Delivery

In some embodiments, the target specific nuclease and blunting enzyme are introduced into a cell as a nucleic acid encoding each protein. The nucleic acid introduced into the eukaryotic cell is a plasmid DNA or viral vector. In some embodiments, the target specific nuclease and blunting enzyme are introduced into a cell via a ribonucleoprotein (RNP).

Preferably, delivery is in the form of a vector which may be a viral vector, such as a lenti- or baculo- or adeno-viral/adeno-associated viral vectors, but other means of delivery are known (such as yeast systems, microvesicles, gene guns/means of attaching vectors to gold nanoparticles) and are provided. The viral vector may be selected from a variety of families/genera of viruses, including, but not limited to Myoviridae, Siphoviridae, Podoviridae, Corticoviridae, Lipothrixviridae, Poxviridae, Iridoviridae, Adenoviridae, Polyomaviridae, Papillomaviridae, Mimiviridae, Pandoravirusa, Salterprovirusa, Inoviridae, Microviridae, Parvoviridae, Circoviridae, Hepadnaviridae, Caulimoviridae, Retroviridae, Cystoviridae, Reoviridae, Bimaviridae, Totiviridae, Partitiviridae, Filoviridae, Orthomyxoviridae, Deltavirusa, Leviviridae, Picomaviridae, Mamaviridae, Secoviridae, Potyviridae, Caliciviridae, Hepeviridae, Astroviridae, Nodaviridae, Tetraviridae, Luteoviridae, Tombusviridae, Coronaviridae, Arteriviridae, Flaviviridae, Togaviridae, Virgaviridae, Bromoviridae, Tymoviridae, Alphaflexiviridae, Sobemovirusa, or Idaeovirusa.

A vector may mean not only a viral or yeast system (for instance, where the nucleic acids of interest may be operably linked to and under the control of (in terms of expression, such as to ultimately provide a processed RNA) a promoter), but also direct delivery of nucleic acids into a host cell. For example, baculoviruses may be used for expression in insect cells. These insect cells may, in turn be useful for producing large quantities of further vectors, such as AAV or lentivirus adapted for delivery of the present invention. Also envisaged is a method of delivering the target specific nuclease and blunting enzyme comprising delivering to a cell mRNAs encoding each.

In some embodiments, expression of a nucleic acid sequence encoding the target specific nuclease and/or the blunting enzyme may be driven by a promoter. In some embodiments, the target specific nuclease is a Cas. In some embodiments, a single promoter drives expression of a nucleic acid sequence encoding a Cas and one or more of the guide sequences. In some embodiments, the Cas and guide sequence(s) are operably linked to and expressed from the same promoter. In some embodiments, the CRISPR enzyme and guide sequence(s) are expressed from different promoters. For example, the promoter(s) can be, but are not limited to, a UBC promoter, a PGK promoter, an EF1A promoter, a CMV promoter, an EFS promoter, a SV40 promoter, and a TRE promoter. The promoter may be a weak or a strong promoter. The promoter may be a constitutive promoter or an inducible promoter. In some embodiments, the promoter can also be an AAV ITR, and can be advantageous for eliminating the need for an additional promoter element, which can take up space in the vector. The additional space freed up by use of an AAV ITR can be used to drive the expression of additional elements, such as guide sequences. In some embodiments, the promoter may be a tissue specific promoter.

In some embodiments, an enzyme coding sequence encoding a target specific nuclease and/or a blunting enzyme is codon-optimized for expression in particular cells, such as eukaryotic cells. The eukaryotic cells may be those of or derived from a particular organism, such as a mammal, including but not limited to human, mouse, rat, rabbit, dog, or non-human primate. In general, codon optimization refers to a process of modifying a nucleic acid sequence for enhanced expression in the host cells of interest by replacing at least one codon (e.g., about or more than about 1, 2, 3, 4, 5, 10, 15, 20, 25, 50, or more codons) of the native sequence with codons that are more frequently or most frequently used in the genes of that host cell while maintaining the native amino acid sequence. Various species exhibit particular bias for certain codons of a particular amino acid. Codon bias (differences in codon usage between organisms) often correlates with the efficiency of translation of messenger RNA (mRNA), which is in turn believed to be dependent on, among other things, the properties of the codons being translated and the availability of particular transfer RNA (tRNA) molecules. The predominance of selected tRNAs in a cell is generally a reflection of the codons used most frequently in peptide synthesis. Accordingly, genes can be tailored for optimal gene expression in a given organism based on codon optimization. Codon usage tables are readily available, for example, at the “Codon Usage Database”, and these tables can be adapted in a number of ways. See Nakamura, Y., et al. “codon usage tabulated from the international DNA sequence databases: status for the year 2000” Nucl. Acids Res. 28:292 (2000). Computer algorithms for codon optimizing a particular sequence for expression in a particular host cell are also available, such as Gene Forge (Aptagen; Jacobus, Pa.), are also available. In some embodiments, one or more codons (e.g., 1, 2, 3, 4, 5, 10, 15, 20, 25, 50, or more, or all codons) in a sequence encoding a Cas protein correspond to the most frequently used codon for a particular amino acid.

In some embodiments, a vector encodes a target specific nuclease and/or a blunting enzyme comprising one or more nuclear localization sequences (NLSs), such as about or more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more NLSs. In some embodiments, the Cas protein comprises about or more than 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more NLSs at or near the amino-terminus, about or more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more NLSs at or near the carboxy-terminus, or a combination of these (e.g., one or more NLS at the amino-terminus and one or more NLS at the carboxy terminus). When more than one NLS is present, each may be selected independently of the others, such that a single NLS may be present in more than one copy and/or in combination with one or more other NLSs present in one or more copies. In some embodiments, an NLS is considered near the N- or C-terminus when the nearest amino acid of the NLS is within about 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 40, 50, or more amino acids along the polypeptide chain from the N- or C-terminus. Typically, an NLS consists of one or more short sequences of positively charged lysines or arginines exposed on the protein surface, bur other types of NLS are known. In some embodiments, the NLS is between two domains, for example between the Cas13 protein and the viral protein. The NLS may also be between two functional domains separated or flanked by a glycine-serine linker.

In general, the one or more NLSs are of sufficient strength to drive accumulation of the target specific nuclease and/or the blunting enzyme in a detectable amount in the nucleus of a eukaryotic cell. In general, strength of nuclear localization activity may derive from the number of NLSs in the target specific nuclease and/or blunting enzyme, the particular NLS used, or a combination of these factors. Detection of accumulation in the nucleus may be performed by any suitable technique. For example, a detectable marker may be fused to the target specific nuclease and/or the blunting enzyme, such that location within a cell may be visualized, such as in combination with a means for detecting the location of the nucleus (e.g., a stain specific for the nucleus such as DAPI). Examples of detectable markers include fluorescent proteins (such as green fluorescent proteins, or GFP; RFP; CFP), and epitope tags (HA tag, FLAG tag, SNAP tag). Cell nuclei may also be isolated from cells, the contents of which may then be analyzed by any suitable process for detecting protein, such as immunohistochemistry, Western blot, or enzyme activity assay. Accumulation in the nucleus may also be determined indirectly.

In some aspects, the invention provides methods comprising delivering one or more polynucleotides, such as one or more vectors as described herein, one or more transcripts thereof, and/or one or proteins transcribed therefrom, to a host cell. In some aspects, the invention further provides cells produced by such methods, and organisms (such as animals, plants, or fungi) comprising or produced from such cells. In some embodiments, a Cas protein in combination with (and optionally complexed) with a guide sequence is delivered to a cell. Conventional viral and non-viral based gene transfer methods can be used to introduce nucleic acids in mammalian cells or target tissues. Such methods can be used to administer nucleic acids encoding a target specific nuclease and/or a blunting enzyme to cells in culture, or in a host organism. Non-viral vector delivery systems include DNA plasmids, RNA (e.g., a transcript of a vector described herein), naked nucleic acid, nucleic acid complexed with a delivery vehicle, such as a liposome, and ribonucleoprotein. Viral vector delivery systems include DNA and RNA viruses, which have either episomal or integrated genomes after delivery to the cell. For a review of gene therapy procedures, see Anderson, Science 256:808-8313 (1992); Navel and Felgner, TIBTECH 11:211-217 (1993); Mitani and Caskey, TIBTECH 11:162-166 (1993): Dillon, TIBTECH 11:167-175 (1993); Miller, Nature 357:455-460 (1992); Van Brunt, Biotechnology 6(10):1149-1154 (1988); Vigne, Restorative Neurology and Neuroscience 8:35-36 (1995); Kremer and Perricaudet, British Medical Bulletin 51(1):31-44 (1995); Haddada et al., in Current Topics in Microbiology and Immunology, Doerfler and Bohm (eds) (1995); and Yu et al., Gene Therapy 1:13-26 (1994).

The target specific nuclease and/or the blunting enzyme can be delivered using adeno-associated virus (AAV), lentivirus, adenovirus, or other viral vector types, or combinations thereof. In some embodiments, Cas protein(s) and one or more guide RNAs can be packaged into one or more viral vectors. In some embodiments, the targeted trans-splicing system is delivered via AAV as a split intein system, similar to Levy et al. (Nature Biomedical Engineering, 2020, DOI: https://doi.org/10.1038/s41551-019-0501-5). In other embodiments, the target specific nuclease and/or the blunting enzyme can be delivered via AAV as a trans-splicing system, similar to Lai et al. (Nature Biotechnology, 2005, DOI: 10.1038/nbt1153). In some embodiments, the viral vector is delivered to the tissue of interest by, for example, an intramuscular injection, while other times the viral delivery is via intravenous, transdermal, intranasal, oral, mucosal, intrathecal, intracranial or other delivery methods. Such delivery may be either via a single dose, or multiple doses. One skilled in the art understands that the actual dosage to be delivered herein may vary greatly depending upon a variety of factors, such as the vector chosen, the target cell, organism, or tissue, the general condition of the subject to be treated, the degree of transformation/modification sought, the administration route, the administration mode, the type of transformation/modification sought, etc.

The use of RNA or DNA viral based systems for the delivery of nucleic acids takes advantage of highly evolved processes for targeting a virus to specific cells in the body and trafficking the viral payload to the nucleus. Viral vectors can be administered directly to patients (in vivo) or they can be used to treat cells in vitro, and the modified cells may optionally be administered to patients (ex vivo). Conventional viral based systems could include retroviral, lentivirus, adenoviral, adeno-associated and herpes simplex virus vectors for gene transfer. Integration in the host genome is possible with the retrovirus, lentivirus, and adeno-associated virus gene transfer methods, often resulting in long term expression of the inserted transgene. Additionally, high transduction efficiencies have been observed in many different cell types and target tissues. Viral-mediated in vivo delivery of Cas13 and guide RNA provides a rapid and powerful technology for achieving precise mRNA perturbations within cells, especially in post-mitotic cells and tissues.

In certain embodiments, delivery of the target specific nuclease and/or the blunting enzyme to a cell is non-viral. In certain embodiments, the non-viral delivery system is selected from a ribonucleoprotein, cationic lipid vehicle, electroporation, nucleofection, calcium phosphate transfection, transfection through membrane disruption using mechanical shear forces, mechanical transfection, and nanoparticle delivery.

In some embodiments, a host cell is transiently or non-transiently transfected with one or more vectors described herein. In some embodiments, a cell is transfected as it naturally occurs in a subject. In some embodiments, a cell that is transfected is taken from a subject. In some embodiments, the cell is derived from cells taken from a subject, such as a cell line. Cell lines are available from a variety of sources known to those with skill in the art (see, e.g., the American Type Culture Collection (ATCC) (Manassas, Va.)). In some embodiments, a cell transfected with one or more vectors described herein is used to establish a new cell line comprising one or more vector-derived sequences.
